C6 Equilibrium Flashcards
What are the three main factors that can change the position of equilibrium?
Concentration, pressure, temperature
These factors influence how the equilibrium position shifts in a chemical reaction.
According to Le Chatelier’s principle, what happens when a factor affecting equilibrium is changed?
The equilibrium position will shift in the direction which counteracts that change
This principle helps predict the direction of the shift but does not explain why it occurs.
What direction does the equilibrium position shift when there are more products than reactants?
To the right
This indicates a favoring of product formation.
When the pressure is increased, the equilibrium shifts towards which side?
Towards the side with less gas molecules
This shift occurs to reduce the pressure.
When the temperature is increased, which way does the equilibrium shift
In the direction of the endothermic reaction
This shift occurs to absorb the excess heat.
When the temperature decreases, which way does the equilibrium shift
In the direction of the exothermic reaction
This shift occurs to release heat.
True or False: Le Chatelier’s principle explains why the equilibrium position shifts occur.
False
It only predicts the direction of the shift.
Fill in the blank: The position of equilibrium shifts to the left if there are more _______ than products.
Reactants
This indicates a favoring of reactant formation.
What does Le Chatelier’s principle summarize regarding shifts in equilibrium position?
It predicts shifts based on changes in concentration, pressure, and temperature
This principle is essential for understanding dynamic equilibria.
What do catalysts do to the rate of reactions?
Catalysts increase the rate of the forward and backward reaction equally.
How do catalysts affect the position of equilibrium?
Catalysts do not affect the position of equilibrium.
What are the goals of industrial chemists in reactions?
The highest possible yields, the fastest rates of reactions, at the lowest possible cost!
